Hi Pr, No idea what the material is - we haven't usd it for a while now, but it was flush & didn't cause any printing problems on double sided reflow. Your board house should know all about it - I would suggest some but ours are all UK or China/Tai

The data we have is from an IBM report. Below 100�C the SAC reliability is almost double that of SnPb (-40 to 100�C thermal cycle). When the upper end temp is increased to 125�C the reliability drops to 75% of SnPb. I'd like to see the data that s

Since these are mounting holes, they're probably all the same size. Why not try rubber plugs shaped like golf tees? Try: * Dempsey Industries; 802 N. 4th St, Miamisburg, Ohio 45342; (937)-866-2345; Gary Pascoe * Shercon somewhere in CA * Harman; 36

As far as I know, the limitations apply to to the manufacturing components, not the equipment per say. At this point there is no set date for the US at the national level. Basically our government is run by big businesses and their effect on our na

Hi Recently i have noticed that after reflow (hot air oven) on the solder lands without components but with solder(screen printing) there is discoloration. It looks like gasolin spilled on the wet road (rainbow). Any idea and reason Ralf

Chunks, For our lead-free eval, we had the same problem with "charred looking" solder paste up the component termination of one of the smaller discretes, coupled with excessive solder balling...this smaller part did see peak temps in the 240 range -

OK all you Gurus here's one for ya. Customer is tinning wires with standard eutectic solder in a solder pot. There is a blue tint to the solder in the pot. After tinning with OA flux, which I will change to NC shortly, he has clear teflon insulation

Hi. Anyone in this forum experienced the lead-free solder paste SAC305 and SAC405? What are the differences to expect for solder paste with SAC305 and SAC405? What is the effect of silver (Ag) alloy in solder paste? It was really appreciated if could

IPC 610 *C* states that the solder thickness requirement is a properly wetted termination is evident. Fillet height is another aspect and is usually specific to the package but is some function of solder thickness plus a percentage of lead height. D

Mike, dude, I feel your pain. Hearing stories like this makes my blood boil! It's almost as ridiculous as a customer who told me to put more solder paste on a MELF component to overcome noise issues - he used more solder paste as antennas to overco
